We assign zeros to the diagonal and the first column in \({S}\)  and set a large value \(\lambda \)  for the other elements. We follow the empirical choice from the implementation of [1]} and set \(\lambda =10^8\)  in our experiments. Formally, the proposed GLC can be formulated as the following:
\(GLC({Q}_e, {K}_e, {V}_e) = Softmax(({Q}_e{K}_e^T - {S}) / \sqrt{D}){V}_e\in \mathbb {R}^{(N+1)\times D}\)
